CORPORATION OF ILLI- PRIMING CUP.

Application i'led May 28,

To all whom t may concern.'

Be it known that I, AUGUST C. DoBRIoK, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Priming Cups, ofwhich the following is a full, clear, and eX- act specication.

My invention is concerned with improvements in priming cups, such forinstance as is shown in my United States Patent No. 1,332,944, datedMarch 9, 1920, and is designed to produce a priming cup, which, when notin use, prevents any possibility of any dirt getting into it and beingcarried through by the oil into the cylinder the next time it is primed.To this end, it consists of a cover attached thereto in such a mannerthat is can be snapped into place and will be securely held covering thecup until it isagain opened to prime the cylinder.

To illustrate my invention I annex hereto a sheet of drawings in whichthe same reference characters are used to designate identical parts inall the figures of which- Fig. 1 is an elevation of my improved cup withthe top portion thereof in central vertical section;

Fig. 2 is a top plan view of the same; and

Fig. 3 is a perspective view of the cover detached; and

Fig. 4 is ay central vertical section showing the valve mechanism. A

The priming cup shown consists of the base portion 10 adapted to bescrewed into the head of a cylinder, or elsewhere, and having a passagetherethrough adapted to be closed or opened at will by a valve formed onthe end of the valve stern 11 screwed therein and provided with apassage therethrough opening into the cup 12 formed on the top of thestem and preferably provided with ears 13 by which it is more readilyturned. rllhe details 0f the internal mechanism of this valve are shownin Fig. 4, and are covered by my Patent No. 1,332,944, issued March 9,1920.

rlhe cover 14, best seen in Fig. 3, is preferably formed of sheet metal,and has the body portion 15 of the proper outline to cover the cup 12,which outline in the present instance is circular. It has the shortpivot piece 16 by which it is secured by the Specification of LettersPatent. anted Aug. 15, 1922..

rivet 17 on one of the ears 13. At the opposite side from the pivotpiece 16 i` is Va projection 18 preferably formed by stamping down someof the material lof the body, and having its' under surface projectinginto the cup, and of such an outline as to fit snugly in the edge of thecup farthest from the rivet 17, so as to prevent the cover fromaccidental movement while not preventing its being intentionally turnedonv its pivot 1'? to open up the cup to pour oil into it. Ipreferablyplace thereon opposite to the projection 16 an upwardlyprojecting j tongue 19 by which the cover is conveniently manipulated.

W hat I cla-im as new and desire to secure by Letters Patent of theUnited States is:

1. In an apparatus of the class described, the combination with apriming cup having a receiving chamber, of a spring metal cover pivotedto one side of the top of said chamber so as to move only in a planeparallel to the top of the receiving chamber, and having a segmentallyshaped projection on the under side thereof adapted to lit into thefurther side only of the chamber top from the pivot to hold the samefrom accidental movement while permitting it to be turned on its pivotwhen desired, the projection being entirely within the chamber when thecover is closed.

, 2. In an apparatus of the class described, the combination with apriming cup having a receiving chamber, of a sheet metal coverv pivotedto one side of the top of said chamber so as to move only in a planeparallel to the top of the receiving chamber, and having a segmentallyshaped projection stamped on the under side thereof adapted to fit intothe further side only of the chamber top from the pivot to hold the samefrom accidental movement 'while permitting it to be turned on its pivotwhen desired, the projection being entirely within the chamber when thecover is closed, and an upwardly projecting tongue, for the purposedescribed.

` In witness whereof, l have hereunto set my hand and aflixed my seal,this 20th day y
